I'd like to raise the rig a bit, mainly so it is better matched to the tow bar height of the motorhome it rides behind.

Right now the height difference is 6 inches, ideally it would be 2" or less, but 4" would be an improvement. So, the ultimate goal is to raise the Liberty at least 2" or more. Less than that doesn't help the problem.

Easiest is to buy larger tires -- if they fit. Anyone have an opinion or even better, direct experience? What is the max tires size that can fit -- note the 18" stock wheels?

And/or, I could lift the body a bit. What is recommended to do this, and what might it cost?

Again, the main goal is to raise the chassis height, with added clearance being a by-product. (Unlike my earlier GPW which I took anywhere/everywhere, this Liberty is limited to Jeep-grade "roads", not crawling.)

Wow. Seems to be the trend on this site. A lot of questions and very little answers. I have been researching this for two years. Still haven't found a definitive answer. I have switched moods to researching different rim/tire combos. Good hunting.

i heard a couple of different things. i heard that with my KK, i can fit 265/70/r16 without a rub bc i also have a lift, but then again i've heard the opposite..... so idk about your size, heck idek about mine lol ill tell you how it goes when i get the lift and tires in
